Water Sensor Detecting Leakage - China

price: contact company for price

FAST-47 WS contact watersensor can provide a relay contact output, when

the height of water immersion rise to 1 mm distance of sensor surface)

touching sensor probe, the relay of sensor will breakover, connecting

external alarm circuit.

The main parameters:

power supply voltage 12 V-24 V (±5%) optional, with polarity protection

No water output Relay contacts off

Have water output Relay contacts on

operating current <20mA

quiescent current <3mA

operating temperature -5℃~+60℃

Relay contacts load capacity (3A 250V AC) (3A 30V DC)

speed of response Faster than 50 milliseconds

Cable wire length 1000 mm , other can be customizable

diameter 47mm

The wiring way:

1: Red - Power ‘+’

2: Black - Power ‘-’

3: Yellow - Relay public feet

4: Green - Relay normal open feet

5: White - Relay normal closed feet


Sensor probe should be downward and vertical to put on detecting liquid level. Process of installing, notice to put sensor at a horizontal terrain.

If detect a little of leakwater, it is not necessary to alarm in exact depth, to put a spongy cushion under watersensor and probe get into spongy cushion, once the spongy cushion inhale water, give out warning.

If need more drive current, it must be extra drive circuit.

If user needs longer cables, contact us to customize cable length.
